Embodiment Construction

[0022] In order to further illustrate the production process and efficacy of the present invention, the illustrations and various test examples are hereby described in detail as follows:

[0023] see Figure 1 to Figure 5 Shown, the present invention prepares the method for the bamboo pulp cellulose nonwoven fabric with deodorizing function with spun-bonded mode, and its step comprises:

[0024] a. Add waste coffee residue (Coffee residue) to bamboo pulp (Bamboo pulp) as a raw material; the waste coffee residue is first ground at a high speed into 500nm-900nm (nanometer) micro-particles and then added to bamboo pulp. The bamboo pulp is selected Ξ±-bamboo pulp cellulose with a cellulose content of more than 50%, the cellulose polymerization degree (degree ofpolymerization, referred to as DP) is between 350 and 750;

[0025]b. Add methylmorpholine N-oxide (N-methylmorpholine N-oxide, NMMO for short, its chemical structure is as follows figure 2 Shown) and phenyl oxazolam (1,3-...

Abstract

The invention relates to a method for preparing deodorizing bamboo pulp cellulose nonwoven fabrics through a spinning-bonding mode. The method comprises the following steps: adding a proper amount of coffee residue into bamboo pulp to be used as a raw material; then adding N-methylomrpholine N-oxide which is called an NMMO solvent for short; mixing and dissolving to obtain a dope; extruding through a spinning opening by the spun-bond mode to form long bamboo cellulose strands; performing air gap cooling and stretching; feeding the long bamboo cellulose strands into solidification liquid to solidify and regenerate; then stretching at a high speed through an airflow stretcher; collecting nonwoven fabrics which are overlapped in a net shape on a collecting net; performing water washing, water-injection rolling, drying and coiling for the net-shaped nonwoven fabric, thus obtaining the continuous long-fiber type deodorizing bamboo pulp cellulose nonwoven fabrics.

Description

technical field [0001] The invention relates to a method for preparing bamboo pulp cellulose nonwoven fabric with deodorizing function by spunbonding, which belongs to the technical field of bamboo fiber manufacturing, and the manufacturing process adopts an environmentally friendly process that will not cause environmental pollution, and the prepared bamboo pulp cellulose The finished spunbonded nonwoven fabric is in the form of long fibers, and has good air permeability, water absorption, and deodorizing properties. It can be used in textiles, medical care, beauty, hygiene materials, filter materials, biotechnology materials, and photoelectric wafer wiping and other uses. Background technique [0002] At present, the largest amount of raw materials used in the production of non-woven fabrics made of man-made synthetic fibers are polypropylene (PP), polyester (PET), polyethylene (PE) and nylon (Nylon). When these large amounts of man-made synthetic fiber non-woven fabrics ...
